LEWIS ALBERT FALLER, OF NASHVILLE, TENNESSEE, ASSIGNOR OF ONE-FOURTH TO STIEF JEWELRY 00., OF NASHVILLE, TENNESSEE.

WATCH-BARREL.

Specification of Letters Patent.'

Patented April 28, 1908.

To all whom it may concern: Be it known that 1, Lewis ALBERT FAL- LER, a citizen of the United States, residing at Nashville, in the. county of Davidson and State of Tennessee, have invented certain new and useful Improvements in- Watch- Barrels; and I do declare thefollowing to be a-full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make'and use the same.

This invention relates to watch barrels and more articularly to the means for securing the barrel in position, and it has for its object to provide a very sim 1e and efiicientmeans of, securing the barre within the movement, as will be hereinafter more particularl set forth. v

In 't e accom'panyin .drawings, which illustrate the invention, igure '1 is a broken sectional view taken through a watch barrel; Fig. 2 is a plan View of the barrel with the inverted perspective view of the hub. y

Referring more articularlyto the drawings, which are for 1 lustrative purposes only, and, therefore, are not drawn to any particular scale, 1. indicates .the plate of a watch and 2 the bridge piece secured thereto. in any ordinary manner. The plate is provided with a circular recess'or cavity, 3, which is provided with a shoulder 4, and the bridge 2 is provided with a recess or cavity 5 and a shoulder 6. These cavities" are arranged to face each other, andthe barrel 7 is mounted therein with its bottom resting onthe shoulder 4, and its top or cover 8 being engaged by'the shoulder 6. The peri hery of the barrel or the lower portion of t e outer surface of the wall 9is adapted to engage with the wall 10 of the cavity 3 above the shoulder 4 and thereby cause the barrel to be held concentrically within said cavity at all times, yet permitting its free rotation when necessary.

1 The bottom of the barrel is rovided with an opening 11 through which t e shouldered ed .to be held against rotation, as by making the openin irregular in outline and forming the hu in corresponding crosssection. The inner end of'the hub is provided with a in engagement with the ottom of the barrel by means of a nut, 15 on the outside the opposite en click wheel for holding the barrel a ainst ro-.

'tation in the ordinary manner. The shoulder 6-01 the bridge 2 is adapted to engage with the cover 8 and thereby hold it against dis lacement.

he hub 13 is hollow or provided with a longitudinal opening through which the main Wheel arbor 16 projects, the ends of the arbor being journaled in the plate 1 and bridge 2 1n the ordinary manner. spring in thebarrel' is connected with the arbor by means of the hub 17 in the usual manner, but is not shown in the drawings, and the arbor is wheel 18. By constructing the parts as above described, it will be evident that the barrel may be arranged ecoentrically or concentrically with the arbor as may be desired, as the opening through the hub 13 may be 'rnade large enou h to permit of its being arranged ecc'entrically to the arbor when desired, as thebarrel is held against lateral movement by the shoulder 10, and does not necessarily depend u on the arbor for its support. By making t e hub as a separate piece, the con- .struction is very much simplified, as it can be madein the usual manner, after which two of its sides, as 19, may be flattened or made parallel with each other and the opening 11 can have two of its walls flattened, as shown at 20, to correspond therewith. The hub is inserted into the barrel from the interior, and the nut screwed onto it upon the exterior of the barrel, and the device is com lete ready 4 for being assembled or united wit the other parts that necessarily coact therewith.

Having describedmy invention, I claim:' 1. In a watch barrel, a substantially cylindrical casing having an opening in itsbottom, two of the Walls of said opening being straight and parallel with each other, a hollow hub in said opening, the body of which is shouldered and has two of its sides flattened to correspond with said straight Walls, the length of said shoulder being less than the thickness of the bottom of the barrel, one end of said hub bein rovided with a'flange and d being screw-threaded, and

The

a screw-threaded click wheel secured upon the barrel a a ted to be engaged by the shoulder in the ridge, ahollow hub through the bottom of the cover provided with a rovided with a shouldered recess flange ugon its inner end and having its outer en screw-threaded, anda click wheel 5 screwed u on said end of the hub and seated between tihe bottom of the barrel and the bottom of the recess in said plate.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- 2 nesses.
